Abstract

Erlotinib is a potent inhibitor of the epidermal growth factor receptor (EGFR) tyrosine kinase, with single-agent antitumor act ivity which improves symptom control and quality of life compared with placebo in non-small-cell-lung cancer (NSCLC) patients. We aimed to determine the efficacy and safety of the second, third or fourth–line erlotinib in advanced NSCLC patients in Turkish populatio n. Eighty patients (33 males and 47 females) were retrospectively evaluated. All patients had received a platinum-based regimen as the first-line metastatic therapy. Most of the patients (62.5%) had received erlotinib as the second-line treatment. None of the pa tients had EGFR mutation studied. One patient achieved a complete response, 10 patients partial response and 21 stable diseases. The overall response rate was 14% and disease control rate was 40%. The median progression-free survival (PFS) and overall survival (OS) were 12 months and 18 months, respectively. Although, there was no survival difference between male and female patients, the median PFS of females was significantly better than male patients (p=0.03). There was no significant difference in disease cont- rol rate in terms of age, smoking status, erlotinib line, performance status (PS), stage and skin rash. The most common adverse events were skin rash (56%), diarrhea (9%) and anorexia (8%). Sixteen patients (20%) developed grade 3 toxicities. Grade 4 toxi city or treatment related interstitial lung disease were not observed. Erlotinib showed an acceptable response rate, survival time a nd to- xicity after disease progression with chemotherapy. It's an alternative therapy as a second or third-line therapy in patients w ith NSCLC. Prospective studies are needed to evaluate the efficiency of the treatment in Turkish population

Özet

Erlotinib tek başına anti-tümör aktiviteye sahip olan güçlü bir epidermal büyüme faktör reseptörü tirozin kinaz inhibitörüdür ve küçük hücreli dışı akciğer kanseri hastalarında plasebo ile karşılaştırıldığında semptom kontrolü ve yaşam kalitesini iyileştirmekted ir. Çalışmamızda, Türk popülasyonunda, ileri evre NSCLC hastalarında ikinci, üçüncü veya dördüncü sıra erlotinib tedavisinin etkinlik ve güvenirliliğini retrospektif olarak değerlendirmeyi amaçladık.Çalışmaya 33 erkek ve 47 kadın, toplam 80 hasta dahil edildi. Tüm hastalar metastatik ilk sırada platin-temelli kemoterapi reji mi almışlardı ve hastaların çoğu (%62.5) erlotinibi ikinci sırada kullanmışlardı. Hiçbir hastada EGFR mutasyonu çalışılamadı. Bir ha stada tam cevap, 10 hastada parsiyel cevap ve 21 hastada stabil hastalık mevcut idi. Genel cevap oranı %14 ve hastalık kontrol oranı%40 idi. Ortanca progresyonsuz sağkalım ve genel sağkalım sırasıyla 12 ay ve 18 ay olarak tespit edildi. Her nekadar, erkek ve kadın hastalar arsında genel sağkalım farkı olmasa da, kadın hastaların ortanca progresyonsuz sağkalımı istatistiksel olarak erkek hastalardan dahi iyiydi (p=0.03). Hastalık kontrol oranı ile yaş, sigara alışkanlığı, erlotinib sırası, performans durumu, başlangıç evresi ve rash arasında istatistiksel bir ilişki tespit edilemedi. En sık görülen yan etkiler döküntü (%56), ishal (%9) ve anoreksi (%8) idi. On altı hastada (%20) grad 3 toksisite gelişmişti. Grad 4 toksisite veya tedavi ilişkili interstisiyel akciğer hastalığı gözlenmedi. Erlotinib,kemoterapi sonrası hastalık progresyonunda kabul edilebilir cevap oranı, sağkalım süresi ve toksisite göstermektedir. NSCLC hastalarında ikin ci veya üçüncü basamak tedavide alternatif bir seçenek olabilir. Türk toplumunda etkinliğini değerlendiren prospektif çalışmalara ihtiyaç vardır.
